The structure of pin thread 220 is described with reference to Fig. 1 and Fig. 4. As shown in Figure 1 and Figure 4, pin thread 220 has the post portion 105 being detained the reception portion P210 reception of 210 keep by mother. As shown in Figure 1, post portion 105 has neck 105a and head 105b. Head 105b is configured to wide cut compared with neck 105a. The circumferential lateral surface of head 105b is laterally with arc shape protuberance, consequently, it is possible to restriction post portion 105 departs from from the reception portion P210 of female button 210. In addition, the opening diameter of the opening P40 of ring bodies 40 is widened by head 105b, it is possible to allow that post portion 105 is inserted into the reception portion P210 of female button 210.

In addition, can be clear and definite according to explanation described later, according to the relative position in the circumference around reception portion P210 between ring bodies 40 and tank body 10, determine that the reception portion P210 of female button 210 keeps the confining force (below sometimes referred to as confining force) in the post portion 105 of pin thread 220. Consequently, it is possible to utilize the above-mentioned confining force of simple structural adjustment. It is not only and can adjust above-mentioned confining force when manufacturing, also can adjust above-mentioned confining force after the fabrication, it is possible to improve the availability/convenience in field widely.

In addition, confining force is when mother detains 210 and pin thread card closes, and makes this card close the power disengaged when applying power to make their (disengagings) separated from each other, at this, owing to confining force is the power keeping fastening state, is therefore called confining force. And, this confining force plays a role when card closes, but certainly also has an impact when closing for card. That is, when confining force is stronger, keep the power of fastening state relatively strong, but when closing for card, compared with the situation that confining force is more weak, it is necessary to power when card closes. Therefore, it is also possible to using confining force as the power required for pin thread and female buckle close, depart from, be called card with joint efforts.

As shown in Figure 1 and Figure 4, pin thread 220 is made up of the tabular component 110,120 utilizing arbitrary method to make shape. As shown in the lower part of Fig. 4, tabular component 110 has base portion 111 and post portion inner wall part 112. Base portion 111 is the part of pressing cloth 230, consists of ring-type, around axis AX. Post portion inner wall part 112 is the barrel along axis AX extension and open at both ends. Post portion inner wall part 112 is the part of through cloth 230. The upper end of post portion inner wall part 112 bends laterally with arc shape, and this part is sticked in tabular component 120.The part bent laterally with arc shape is called bend 113.

Tabular component 120 has base portion 121 and post portion outside wall portions 122. Base portion 121 is the part of pressing cloth 230, consists of ring-type, surrounds axis AX. Post portion outside wall portions 122 is that lower end is uncovered, the part of upper end closed, and the outer peripheral edge of its upper end is with arc shape to lateral bend outside radius direction, and this part is sticked in tabular component 110. It is called bend 123 to the part of lateral bend outside radius direction by with arc shape. Being blocked by the bend 123 of the bend 113 of post portion inner wall part 112 and post portion outside wall portions 122 and close, tabular component 110 and tabular component 120 are locking mutually.

Cloth 230 by base portion 111 and base portion 121 from clamping up and down. When utilizing base portion 111 and base portion 121 clamps cloth 230, pin thread 220 is carried out pressing process, base portion 111 is provided with multiple recess 115, base portion 121 is provided with multiple protuberance 125. Consequently, it is possible to pin thread 220 is fixedly mounted on cloth 230. In addition, as shown in the upper part of Fig. 4, pin thread 220 carries out pressing process at 6 places around axis AX symmetry.

The structure of the rotation scope of restriction rotator 50 is described with reference to Fig. 5 and Fig. 6. Fig. 5 represents the cross section structure along the single-point line X5-X5 shown in Fig. 6 of rotator 50 and tank body 10, and Fig. 6 represents the cross section structure of the line X6-X6 of the single-point along Fig. 5 of female button 210. As shown in Figure 5, the circumferential lateral surface at rotator 50 is provided with in pre-determined range in the circumferential continuous print groove portion 55, and at the upper expanded range of circumference, by stopping, end 55a, 55b limit in groove portion 55. The cylinder portion 12 of tank body 10 is provided with and is configured in groove portion 55 and the stop 12p collided of stopping end 55a, 55b in intended groove portion 55. Shown in Fig. 5 time, stop end 55b and meet stop 12p, consequently, it is possible to forbid that rotator 50 turns clockwise further. Stop 12p is met, it is possible to forbid the counterclockwise rotation of rotator 50 by stopping end 55a. By limiting the rotation scope of rotator 50 like this, two closed positions (rotation stop position) that rotator 50 stops can be set, it is possible to adjust the confining force (this point according to explanation described later can clearly) of the reception portion P210 of female button 210 accordingly with each closed position.

As shown in Figure 6, circumferential lateral surface at ring bodies 40 is also provided with the groove same with rotator 50. Owing to ring bodies 40 rotates together with rotator 50, thus, it would be desirable to the rotation scope that also limit ring bodies 40 same with rotator 50. In addition, stop 12p is not necessarily the cylinder portion 12 self of tank body 10, it is also possible to be other component. The concrete form of the rotation scope of restriction ring bodies 40 and rotator 50 is arbitrary, except can utilizing the rotation scope that tank body 10 limits ring bodies 40 and rotator 50 as described above, it is also possible to utilize the rotation scope of cover 30 restriction rotator 50.

The structure correspondingly adjusting reception portion P210 with ring bodies 40 and tank body 10 relative position in the circumferential and keeping the power in post portion 105 is described with reference to Fig. 7 and Fig. 8. Fig. 7 and Fig. 8 is the horizontal cross of the X7-X7 along Fig. 1 of ring bodies 40, tank body 10 and fixing body 20. Also suitably it is described with reference to Fig. 9��Figure 11 simultaneously.

As shown in Figure 7, ring bodies 40 has mutually different diameter R40, R41, meets diameter R40 > diameter R41. The part corresponding with diameter R40 is called the portion's of being touched (being called pressed portion in the explanation of the mode of enforcement) 40m.As shown in Figure 7, pressed portion 40m is protuberance 40m1,40m2 protruding outside to radius direction. Protuberance 40m1,40m2 are arranged with 180 degree of intervals in the circumferential, and outstanding to opposition side mutually.

As shown in Figure 7, tank body 10 has mutually different internal diameter R10, R11, meets internal diameter R10 < diameter R11. The part corresponding with internal diameter R10 is called contact part (being called press section in the explanation of the mode of enforcement) 10m. As shown in Figure 7, press section 10m is protuberance 10m1,10m2 outstanding inside radius direction. Protuberance 10m1,10m2 are that a portion 12 is recessed into inside radius direction, part outstanding in the same direction. Protuberance 10m1,10m2 are arranged with 180 degree of intervals in the circumferential.

Shown in Fig. 7 time, the pressed portion 40m of the ring bodies 40 and press section 10m of tank body 10 is not facing, does not limit ring bodies 40 and is out of shape outside radius direction. In order to conveniently, this state is called " weak buckling state ". On the other hand, shown in Fig. 8 time, the pressed portion 40m of the ring bodies 40 and press section 10m of tank body 10 is facing, and restriction ring bodies 40 is out of shape outside radius direction. In order to conveniently, this state is called " strong buckling state ". Compared with " weak buckling state ", " strong buckling state " is the state being not easy to insert or extract. Respective state shown in Fig. 7 with Fig. 8 is such as corresponding with the clockwise closed position of rotator 50 and the counterclockwise closed position of rotator 50 (with reference to Fig. 5 and relative explanation). That is, when being sticked in female button 210 in post portion 105, being less than the diameter of the head 105b in post portion 105 due to the diameter of opening P40, therefore, post portion 105 makes ring bodies 40 elasticity be out of shape in the way of the diameter of enlarged openings P40. After head 105b have passed opening P40, ring bodies 40 elastic reset, opening P40 recovers to be sticked in neck 105a for original diameter. In addition, the diameter of neck 105a is less than the diameter of head 105b, and the minimum diameter being less than opening P40 is then better. Under " strong buckling state ", it is possible to suppressing the enlarged-diameter of opening P40, therefore, compared with " weak buckling state ", head 105b is difficult to by opening P40.

In addition, whether when the pressed portion 40m of the ring bodies 40 and press section 10m of tank body 10 is facing, it is arbitrary for making pressed portion 40m contact with press section 10m. In addition, when making both contact, it is possible to make the opening shape of ring bodies 40 such as be deformed into ellipse from positive round, owing to the length size of the minor axis of ellipse is less than positive circular diameter, accordingly, it may be possible to guarantee stronger confining force. When confining force is stronger, it is possible to additionally limit pin thread 220 from the disengaging of female button 210. When confining force is more weak, additionally do not limit pin thread 220 from the disengaging of female button 210. Those skilled in the art are certainly clear, it is also possible to weak buckling state is called unlock state, and strong buckling state is called locking state.

When " the weak buckling state " illustrated in Fig. 7, do not limit ring bodies 40 to be out of shape outside radius direction, therefore, the operation in the post portion 105 that the reception portion P210 detaining the post portion 105 inserting pin thread 220 in the reception portion P210 of 210 and certainly female button 210 to mother extracts pin thread 220 is not difficult.

As shown in Figure 9 and Figure 10, when the head 105b in post portion 105 is pressed into the opening P40 of ring bodies 40 from below, utilizing ring bodies 40 to the distortion outside radius direction, the opening diameter of this opening P40 starts to expand from initial opening diameter.Between the pressed portion 40m of ring bodies 40 and the inner circumferential side in the cylinder portion 12 of tank body 10, there is gap, thus, allow that ring bodies 40 is out of shape, it is possible to guarantee that the enlarged degree of opening P40 allowed by tank body 10 is bigger. The head 105b in post portion 105 is pressed into from top the situation of the opening P40 of ring bodies 40, be that is the situations that female button 210 is separated with pin thread 220 is also the same. In addition, ring bodies 40, when not being be subject to pushing outside radius direction from place of post portion 105, recovers as original shape, and the opening diameter of opening P40 recovers as initial opening diameter from the opening diameter expanded.

When " the strong buckling state " illustrated in Fig. 8, the pressed portion 40m of the ring bodies 40 and press section 10m of tank body 10 is facing, it is in the state that the distortion of ring bodies 40 is restricted, that is compared with " weak buckling state ", the deformation extent allowed by tank body 10 of ring bodies 40 is less, and the enlarged degree of the opening P40 allowed by tank body 10 of ring bodies 40 is less. Thus, and it is not easy to extract post portion 105 from the reception portion P210 of female button 210, equally, and it is not easy to detain to mother in the reception portion P210 of 210 and inserts post portion 105. In addition, it is not easy to refer to the problem of degree, impossible meaning is not referred to.

As shown in figure 11, when the head 105b in post portion 105 to be pressed into the opening P40 of ring bodies 40 from top, the pressed portion 40m of ring bodies 40 moves outside radius direction, but it is returned to thruster in radius direction by the press section 10m of tank body 10, result is that ring bodies 40 is restricted to the distortion outside radius direction, the opening diameter of the opening P40 that can limit ring bodies 40 expands, and the maximum open amplitude of the opening P40 allowed by tank body 10 is less. The situation that the head 105b in post portion 105 is pressed into the opening P40 of ring bodies 40 from below is also the same.

According to the above description can be clear and definite, in the present embodiment, can with the press section 10m of the pressed portion 40m of ring bodies 40 and tank body 10 relative position in the circumferential correspondingly adjust ring bodies 40 allowed by tank body 10 opening P40 enlarged degree, it is possible to the reception portion P210 of the female button 210 of adjustment keeps the confining force in the post portion 105 of pin thread 220. The concrete form of the distortion of restriction ring bodies 40 is arbitrary. But, by applying flexibly the cylinder portion 12 with the surrounding wall portion around ring bodies 40 as in the present embodiment, it is possible to utilize the distortion of simple structural limitations ring bodies 40.

In addition, according to the above description can be clear and definite, in the present embodiment, it is possible to adjust above-mentioned confining force on arbitrary opportunity. Bluntly say, even after manufacturing female button 210, it is also possible to by supplying revolving force and make ring bodies 40 rotate to rotator 50. The ring bodies 40 being such as in the angle position shown in Fig. 7 is rotated to the angle position shown in Fig. 8. Consequently, it is possible to turn into strong buckling state from weak buckling state. Thus, after making female button 210 and pin thread 220 block conjunction under weak buckling state, cannot easily extract pin thread 220 by turning into strong buckling state. This is an example, but can be used in prevention methods. In addition, the reception portion P210 of female button 210 keeps the confining force in the post portion 105 of pin thread 220 might not be defined in two ranks, it is also possible to be more than two ranks.

As long as compareing above-mentioned explanation, those skilled in the art just can specify the manufacture method of snap-fastener 200. Addedly being described, female button 210 such as can utilize following step to manufacture.First, opening is set in cloth 230, in this opening, inserts fixing body 20. Secondly, make fixing body 20 and tank body 10 integration, configure ring bodies 40 and rotator 50 in tank body 10 inner stacks, utilize cover 30 from top closed tank 10, make the lower ends bent of the periphery sidepiece 32 of cover 30. Pin thread such as can utilize following step to manufacture. Cloth 230 arranges opening, the tabular component 110 of the shape of insertion shown in Fig. 1. Then, the tabular component 120 of the shape shown in Fig. 1 is made to be sticked in tabular component 110. Afterwards, above-mentioned pressing process is utilized to be securely fixed on cloth 230 by pin thread 220. The manufacturing step of snap-fastener 200 depends on machinery/instrument etc. that manufacture adopts to a great extent.

8th enforcement mode

With reference to Figure 29��Figure 32, the 8th enforcement mode is described.In the above-described embodiment, ring bodies is made up of single annular resilient material. On the other hand, in the present embodiment, ring bodies is divided into multiple component, utilizes the change of the configuration space between each component forming ring bodies to realize the distortion of ring bodies. In this case, ring bodies also can recover as original shape by utilizing the elasticity components such as spring, it is possible to obtains the effect same with above-mentioned enforcement mode. As long as using metallic substance on the member of formation of ring bodies, just can improve the intensity of member of formation, promoting the weather resistance of snap-fastener. In the present embodiment, ring bodies is divided into two parts, utilizes the leaf spring of elasticity component to be linked up by these two portions. But, the quantity being divided into of ring bodies is arbitrary, it is possible to be divided into the part of more than 3. The concrete form flexibly connecting each several part being divided into is arbitrary, might not be defined in leaf spring described later.

In addition, according to press section 10m and pressed portion 40m relative position in the circumferential, be in other words relative to tank body 10 rotation in the circumferential according to ring bodies 40, deformation extent at the ring bodies 40 allowed by tank body 10 changes this point and the enlarged degree of the opening P40 of ring bodies 40 allowed by tank body 10 changes in this point, is same with above-mentioned enforcement mode.

Figure 29 is the sectional view of the single-point line X29-X29 along Figure 30. Figure 30 is the horizontal cross of the outline of the line X30-X30 of the single-point along Figure 29 of female button. Figure 31 is the sectional view of the outline of the line X31-X31 of the single-point along Figure 29 of female button. Figure 32 is the horizontal cross of the outline of the state after the position 90-degree rotation shown in Figure 30 of female button. Figure 30 is equivalent to the situation of Fig. 7 of the 1st enforcement mode. Figure 32 is equivalent to the situation of Fig. 8 of the 1st enforcement mode.

As shown in Figure 29��Figure 32, ring bodies 40 comprises letter U shape portion 45p and the letter U shape portion 45q that annular component is divided into two and obtain, and it is that this letter U shape portion 45p, 45q utilize leaf spring 47,48 to link up and form. As shown in figure 30, letter U shape portion 45p, 45q overlook the part in letter U shape, and the part caving in into letter U shape is oppositely disposed in the way of facing one another. Communicating pores 46a, the 46b through on direction of running through in post portion it is respectively equipped with in two ends of letter U shape portion 45p. Two end portion at letter U shape portion 45q are provided with communicating pores 46c, the 46d through on direction of running through in post portion. The leaf spring that the mutual elasticity in letter U shape portion separated links up is arranged by these openings in order to insert to fix. As holding according to Figure 31, leaf spring 47,48 is configured to letter U shape, has two insertion ends. Typically, leaf spring is metal, but is not limited thereto, it is possible to think resin-made.

By being oppositely disposed in the way of facing one another by two letter U shape portions 45p, 45q as individual member, it is determined that the out opening P40 of ring bodies 40, the post portion of pin thread is inserted in this opening P40, and ring bodies 40 and post portion card close. About pin thread post portion insertion, card close, ring bodies (the 1st component) for annular component be a preferred example.

Such as, the 1st component can also by taking axis AX as the independent component (not utilizing the component of the integrations such as leaf spring) that symmetry axis is relative is formed. In this case, on the configuration direction of each component, size (interval) between each component is less than the size in the same direction of head usually, this size of head it is greater than (when allowing that post portion inserts) when card closes, and, recovered as common interval by interval between each component afterwards at head, consequently, it is possible to allow head by closing with card.In addition, centered by axis AX configuration multiple components, be such as two relative components or in the circumferential every 120 �� configuration 1 component 3 components, in the circumferential every 72 �� configuration 1 component 5 components etc. That is, configure more than at least 1 component in the circumferential in the post portion of public component, on the direction leaving axis AX, on coaxial, it is configured with the 2nd component in the outside of component. The concrete form making each component return to original position is arbitrary, illustratively says, it is possible to list elasticity components such as utilizing spring.

As shown in figure 30, two insertion ends of leaf spring 47 are inserted in communicating pores 46a, 46c respectively. Two insertion ends of leaf spring 48 are inserted in communicating pores 46b, 46d respectively. Thus, letter U shape portion 45p and letter U shape portion 45q elasticity in the plane orthogonal with the depth direction of reception portion P210 links. When the post portion 105 of pin thread 220 is inserted in the reception portion P210 of female button 210, letter U shape portion 45p and letter U shape portion 45q respectively can to radius direction lateral displacement, it is possible to guarantee that width between the two expands. When not utilizing the post portion 105 of pin thread 220 to press, letter U shape portion 45p and letter U shape portion 45q along with leaf spring 47,48 shape recover and to radius direction medial displacement, width between the two returns to initial value.

In the present embodiment, letter U shape portion 45p, 45q are metal, and both flexibly combine. The letter U shape portion of metal also can fully stand the crimping repeatedly in the post portion 105 of pin thread 220, and thus, the weather resistance of female button 210 rises. Further, when the state shown in Figure 32, due to compared with the situation of resin-made, it is possible to be limited in letter U shape portion produce distortion amount, therefore, not easily when mother detain 210 link with pin thread about 220 both are separated. Even if letter U shape portion obtains to the pressure outside radius direction from the post portion 105 of pin thread 220, it is also possible to the interval of restriction letter between U-shaped portion 45p, 45q expands. In the present embodiment, by utilizing the rotation of ring bodies 40 to become the state shown in Figure 32 from the state shown in Figure 30, it is possible to firmly lock the link of female button 210 and pin thread 220.

Figure 39 is the vertical sectional view of the outline of the line X39-X39 of the single-point along Figure 38 of female button of locking state.

It is different that present embodiment the 8th implements mode, utilizes the leaf spring 49 circumferentially extended between ring bodies 40 and tank body 10 to guarantee the force in the letter U shape portion 45 obtained because being divided into two for ring bodies 40.In this case, it is also possible to obtain the effect same with above-mentioned enforcement mode. By adjusting the length of leaf spring 49, it is possible to guarantee suitable spring power easily, and be easy to guarantee the spring power of abundant size. Moreover, it is possible to the card that the increase utilizing spring power makes mother buckle 210 makes a concerted effort to increase. Also the increase of spring power can be expected to utilize to improve and female to buckle 210 for the resistance of Reusability.

In addition, in the present example, as shown in figure 36, each leaf spring 49 is spaced between two protuberances 10m1,10m2 with 180 degree in the circumferential. Each leaf spring 49 links and be shifted in the circumferential with the rotation of rotator 50, is configured in as shown in figure 38 than two protuberances 10m1,10m2 by the position inside radius direction.

In the present embodiment, as shown in figure 34, letter U shape portion 45p, 45q utilize leaf spring to be connected, but are defined as letter U shape portion 45p, 45q and combine loosely because of play between the two. Compared with the 8th enforcement mode, it is not necessary to letter U shape portion 45p, 45q are linked up each other, accordingly, it may be possible to seek to simplify the assembling of female button 210.

In addition, according to press section and pressed portion relative position in the circumferential, be in other words relative to tank body 10 rotation in the circumferential according to ring bodies 40, the change enlarged degree of the opening P40 allowed by tank body 10 of this point and ring bodies 40 of the deformation extent allowed by tank body 10 at ring bodies 40 changes in this point, is same with above-mentioned enforcement mode.

As shown in figs. 33 and 34, the ring bodies 40 being configured in tank body 10 is made up of one group of letter U shape portion 45p, 45q. End face in one end of letter U shape portion 45p is provided with convex fitting portion 45p1, end face at the other end of letter U shape portion 45p is provided with recessed shape fitting portion 45p2, and the central part upper surface of the central authorities between the two ends of letter U shape portion 45p is provided with insertion projection 45p5 highlightedly. Insertion projection 45p5 can be inserted in the portion that the is inserted into 500p of the recessed shape of the bottom surface of the rotator 50 being configured on ring bodies 40. The structure of letter U shape portion 45q is same with letter U shape portion 45p, omits and repeats explanation. In addition, projection 45p5 is corresponding with the convex fitting portion 45p1 of letter U shape portion 45p, recessed shape fitting portion 45p2, insertion respectively for the convex fitting portion 45q1 of letter U shape portion 45q, recessed shape fitting portion 45q2, insertion projection 45q5.

The convex fitting portion 45p1 of letter U shape portion 45p is embedded in the recessed shape fitting portion 45q2 of letter U shape portion 45q loosely, the protuberance 45q1 of letter U shape portion 45q is embedded in the recess 45p2 of letter U shape portion 45p loosely, consequently, it is possible to guarantee the expansion at the interval that letter U shape portion 45p and letter U shape portion 45q is mutual and reduce, be in other words the expansion of the opening amplitude of the opening P40 of ring bodies 40 and reduce.

As shown in Figure 33 and Figure 35, in tank body 10, it is provided with one group of leaf spring 49p, 49q accordingly with above-mentioned one group of letter U shape portion 45p, 45q. As shown in figure 35, leaf spring 49p is the metal sheet of the constant thickness that initial attitude is smooth. The insertion sheet 49p6 that leaf spring 49p has a dull and stereotyped portion 49p5 of strip and the central authorities at the two ends of flat board portion 49p5 are arranged highlightedly. The structure of leaf spring 49q is same with leaf spring 49p, omits and repeats explanation.

Also add and it is described with reference to Figure 36. Leaf spring 49p is configured between letter U shape portion 45p and tank body 10, this flat board portion 49p5 is forced to bend to arc shape between the circumferential lateral surface and the inner circumferential side of tank body 10 of letter U shape portion 45p, makes the dull and stereotyped portion 45p5 of leaf spring 49p form the spring power being recovered the original shape for straight line shape.Leaf spring 49q is configured between letter U shape portion 45q and tank body 10 too, forms the spring power equal with the spring power of leaf spring 49p. When by leaf spring as the force source that letter U shape portion 45 is exerted a force inside radius direction, the continuous print space in the circumferential between ring bodies 40 and tank body 10 can be utilized, the length more fully being easy to guarantee leaf spring, is that is applicable to guaranteeing spring power more fully.

As shown in (a) of Figure 36, the dull and stereotyped portion 49q5 of leaf spring 49q is applied in the spring power allowing its each end to radius direction lateral displacement. Letter U shape portion 45q is exerted a force inside radius direction along with the inner circumferential side of each end press tank body 10 of the dull and stereotyped portion 49q5 of leaf spring 49q. Equally, the spring power of letter U shape portion 45p and leaf spring 45p is correspondingly exerted a force inside radius direction. Like this, it is possible to guarantee and maintain the original state that the closedown of letter U shape portion 45p and letter U shape portion 45q, configuration space between the two are minimum.

The insertion sheet 49p6 of leaf spring 49p together can be inserted into the insertion projection 45p5 of letter U shape portion 45p in the portion that the is inserted into 500p of the recessed shape of the bottom surface of rotator 50.
